LUBRIGATING ATTACHMENT FOR JOURNAL-BOXES.

Application filed March 13, 1911.

To all whom it may concern Be it known that we, GEORGE E. PARKS and STEPHEN E. PARKS, citizens of the United States, residing at Pillager, in the county of Cass, State of Minnesota, have nal box or in connection with any journal to which it may be adapted.

The object of the invention is to provide a simple and eflicient means for carrying the lubricating oil frointhe bottom of the box or other reservoir, to the journal in such manner as to insure a proper supply A further object of the invention is to eliminate the necessity for use of Waste, felt, or other type of wick with their corresponding disadvantages. V

A further object of the invention is to provide means for preventing splashing of the free body f lubricating oil.

In the drawings forming a portion of the specification and in which like numerals of reference indicate similar parts in the sev eral views, Figure 1 is a section taken Vere tically and longitudinally of a journal box with the lubricating attachment therein, the journal, the lubricating j roller and other parts being in elevation. Fig. 2 is a transverse vertical section through the journal box, the left hand portion of the attach ment being in elevation while the right hand portion is in transverse vertical section. Fig. 3 is a section on line 3-3 of Fig. "2, the attachment being shown in top plan and the position of the journal thereabove being indicated in dotted lines. Fig. 4 is a perspective view of the combined lubricating roller support and baffle plate or ,anti-splasher.

Fig. 5 is a vertical section taken longitudi nally through the lower portion of a journal box with the journal in elevation, and

showing partly in section and partly in elevation the use of a modified form' of lubricating or distributing roller. F ig. 6 is an elevation showing a further modification of lubricating or distributing roller.

Referring now to the drawings, there is shown a common type'of journal box having upon the floor of the oil pit or container a plurality of upwardly directed studs 10,

four in number, the box having the further additions of two ribs 11 which project from the side walls of the lower portion of the journal box at points midway of the length.

of the oil pit and extend to points some what short ofthe height of the lower face of the journal 12.

Instead of packing the oil pit with waste for carrying the lubricant to the journal, there is employed a lubricating or distributmg roller 14 having trunnions 15 at its ends which-are rotatabl mounted in the bearin s 16 and 17 of a supporting or carrying plate 18 which is in the form of a hollow frame. The plate or frame 18 has at one end the integral depending bearing 16 above referred to and at the opposite end the removable depending bearing 17 held to the under sideof the frame by screws 19 or in any other suitable manner to facilitate ready application and removal of it.

As shown inFigQ of the drawings and also in Fig. 3, the width of the opening 20 of theframe 18 is somewhat less than the diameter of the distributing roller while the roller, these last correlative dimensions per mitting a slight longitudinal movement of the roller in the frame to meet correspond ing longitudinal movement of thejournal 8 in the journal box.

By reason of the width of the opening 20 being less than the diameter of the distributing roller and the fact that as shown in Fig. 2 of the drawings, the frame in practice lies above the axis of the distributing roller, it is necessary to apply the distributing roller t0 the frame from the bottom and it is because of this that the bearing 17 is made removable. It is of course understood that the trunnion at one end of the distributing roller is slid into the bearing 16, the rollers then raised into the opening of the frame and the bearing 17 is then adjusted under the opposite trunnion and then fastened to the under side of the frame as above described.

In the sides of the frame are notches 21 which receive the ribs 11 respectively and by which engagement the frame is held against longitudinal displacement in the journal box, it being understood of course that when the frame is raised clear of the ribs it may be drawn longitudinally from the box.

The frame or plate 18 is yieldably sustained with the distributing roller in contact with the journal 12, by means of helical springs 22 one of which is disposed at each corner of the frame or plate with its lower end engaged over one of the studs 10 while its upper end receives a corresponding stud 23 that depends from the frame.

In use, lubricating oil is supplied to the box in a free state and in a quantity sufficient to reach to any point up to the plate or frame 18, it being understood of course that there must be enough oil to permit the distributing roller to dip into it.

As hereinbefore explained, the width of the opening in the frame 18 is less than the diameter of the distributing roller and upon reference to Fig. 2 it will be noted that the side edges of the opening lie very close to the surface of the roller. Thus, the frame or plate 18 effectively serves as a battle and prevents splashing 0r surging of the oil and consequent waste through the end openings of the box.

It is found in practice that the springs 22 serve to hold the distributing roller in intimate contact with the journal so that the latter is supplied with oil in quantity suilicient to insure proper lubrication at all times. i

In Fig. 5 of the drawings there is shown a modification of the distributing roller in the form of a spring wire helix 25 the end portions of which are fixed to an axle 26 which is journaled in a frame 27 supported upon springs 28 in the same manner as the structure hereinbefore described. In this form of roller the oil is supplied to the journal helically and the spring quality of the roller is utilized to insure intimate contact with the journal under various working conditions. Furthermore, when the distributing roller is traveling at a high rate of speed, the oil that is taken up on the inner surface of the wire of the helix, passes comparatively gradually to the outer surface and thus is not thrown off by centrifugal action before it reaches the bearing brass illustrated at 29 in Fig. 2 andin Fig. 1, which brass is an element of the ordinary journal in the formation of the end convolutions in mutual contact, thus insuring a greaterquantity of lubricant to the end portions of the journal where it is most needed, than to the intermediate portions.

It will thus be seen that there is provided 7 0 an attachment which may be used in various types of journal boxes and which will deliver oil to the journal in ample quantity under all conditions of use. Furthermore,

the entire oil pit, with the exception of the room occupied by the attachment, will be utilized to contain oil. Thus a greater quantity can be carriedin the box than when waste is used, and refilling is more seldom required. This permits of positive sealing of the box lid in place and the positive prevention of ingress of foreign matter, with the well understood advantages.

Vhat is claimed is:

The combination with an axle, of an axle 8 box therefor adapted to receive lubricating oil, a fiat plate located within the axle box beneath the axle and having a rectangular opening therein, means for retaining the plate from lateral movement in the box, the

ends of said plate having depending U- shaped sockets, an oil distributing roller of relatively greater cross diameter than the opening in the plate provided with studs at the end thereof adapted to seat in the sockets whereby the roller is rotatably mounted in the plate with the major portion of theroller lying below the plate, the construction being such that the splashing and escaping of oil in undesired quantities abovethe plate is avoided, and vertically disposed coil springs interposed between. the underside of the plate and the bottom of the axle box and normally holding said plate in position to cause the roller to hear at its upper portion against the axle.

In testimony whereof, we ailix our signatures in presence of two witnesses.
